Creating my own version of EQ library [Resolved]
Hi all.
I know how to do basic RPL programming, but have not yet tried ASM or SystemRPL. I wanted to create my own equation library, but I wanted to use same functionality as the original EQ lib which is very good. Would like to be able to do the following: 1. Reproduce the menu with filled vs not filled icons (see screenshot). 2. Reproduce that square box that shows the value has been input (see screenshot). 3. Reproduce the shortcut LeftShift+Menu Item to perform the calculation. Is that something I can do with UserRPL? Or do I need to do it by hand in ASM/SystemRPL? Are there any examples of others that have done it that I could base on? Can someone please point me toward the right direction? Thank you!

RE: Creating my own version of EQ library
I did end up finding a good source and working example.
http://edspi31415.blogspot.com/2021/07/h...rand.html This worked very well using the MSOLVR. The only thing I am still missing is that the MSOLVR is for multiple equations. I wanted to be able to do the same with only one.

RE: Creating my own version of EQ library
I think I can close my own thread.
In case someone ever come here looking for the same thing, here is a sample code that has 2 SOLVE solutions, one for single equation and another for multiple equation. Just created a simple Ohm's law example to illustrate. « { {"Mult" « { V I R P} PURGE @clear older variables 0_V V STO @set units 0_A I STO 0_R R STO 0_W P STO 'V=I*R' 'P=V*I' 2 >LIST STEQ MINIT @Convert to list and store equations  replace > with actual arrow "Ohm Law" @Show the name of the equation in the top of the screen {V I R P} MITM @Order Variables MSOLVR »} @Start solver {"Singl" « { V I R } PURGE @clear previous vars 0_V V STO @set units 0_A I STO 0_R R STO 'V=I*R' STEQ @store equation 30 MENU @start solver »} } TMENU»
